The current voltage relation of diode is given by $\;(I=e^{\large\frac{1000V}{T}-1})mA\;$ , where the applied voltage V is in volts and the temperature T is in degree kelvin .If a student makes an error measuring $\;\pm0.001 V\;$ while measuring the current of 5 mA at 300 K , what will be the error in the value of current in mA ?

Question

$(a)\;0.2 \;mA \qquad(b)\;0.02\; mA\qquad(c)\;0.5\; mA\qquad(d)\;0.05\; mA$
